In these lessons, we will look into two methods that can be used for metric conversion problems. The first method uses the metric table and can also be regarded as a shortcut method. The second method uses the unit fraction method.

The following diagrams show some metric conversions for lengths and weights. Scroll down the page for examples and solutions.

### Method 1

Each prefix differs by a multiple of 10 from the next prefix. When converting between the different units of measure, we look at the number of “jumps” between the prefixes of the two units and then multiply or divide by the powers of 10 accordingly (moving to the right would mean to multiply and moving to the left would mean to divide).

**How to perform metric conversion using the table method or shortcut method?**

Examples:

1. 7m to cm

2. 15L to mL

3. 30000mg to g**How to convert metric units of weight without using a calculator?**

The presentation focuses on conversion between kg, g, and mg.

Imagine a 1 kilogram(kg) tablet which is made up of a 1000 smaller gram(g) tablets which is in turn made up of 1000 even smaller milligram (mg) tablets.

This tutorial explains answers to exercises in converting metric units of weight. The exercises involve multiplying and dividing without a calculator.**How to convert to different metric units of measure for length, capacity, and mass?**

The**metric system** is widely used because it is based on the powers of 10. It allows for easy conversion between smaller and larger units.

The basic unit of length is the**meter**(m). It is just over 1 yard.

The basic unit of weight is the**gram**(g). One gram is the mass of 1 cubic centimeter of water.

The basic unit of capacity or volume is**liter**(l). A liter equals 1000 cubic centimeters.

Examples:

Complete each conversion

1. 6.3km = ____ m

2. 62,300cm = ___ hm

3. 37,200g = ___ kg

4. 1.73hg = ___ dg

5. 93.7L = ___ mL

6. 62,300cL = ___ kL

**How to use the metric staircase to convert units within the metric system?**

Another method similar to the table method is to use the metric staircase. It is also called the ladder method.

**How to use the metric staircase to convert between metric measurements?**

When you go up the stairs to the left, move the decimal to the left.

When you go down the stairs to the right, move the decimal to the right.### Method 2

The following diagrams show some metric conversions for lengths and weights. Scroll down the page for examples and solutions.

The metric system uses prefixes to denote multiple of 10.

The following table shows some common prefixes.

Prefix | kilo | hecto | deka | unit | deci | centi | milli |

Symbol | k | h | da | d | c | m | |

1,000 | 100 | 10 | 1 meter liter gram |
0.1 | 0.01 | 0.001 |

** Example: **

Convert 3 km to m

** Solution: **

There are 3 “jumps” to the right from kilometer to meter.

So, we multiply by 10^{3} = 1000

3 km = 3 × 1,000 = 3,000 m

** Example: **

Convert 20 mm to cm

** Solution: **

There is 1 “jump” to the left from millimeter to centimeter

So, we divide by 10.

20 mm = 20 ÷ 10 = 2 cm

Examples:

1. 7m to cm

2. 15L to mL

3. 30000mg to g

The presentation focuses on conversion between kg, g, and mg.

Imagine a 1 kilogram(kg) tablet which is made up of a 1000 smaller gram(g) tablets which is in turn made up of 1000 even smaller milligram (mg) tablets.

When you go up the stairs to the left, move the decimal to the left.

When you go down the stairs to the right, move the decimal to the right.

In this method, we multiply by a unit fraction in order to perform the metric conversion.
